Hello: I am trying the free hands on Bridge Master and in many of them GIB is not following suit on me (perhaps when I am playing the wrong card). For instance in 4 A-3: 1) Heart J-3-7-A 2) 8C lead from South, 6C, KC, 5C 3) 2C lead from North, 6S(!) from East! vs 1) same 2-5) Clear diamond tricks, def discard spades 6) 2C lead from North, 5C, AC, 6C 7) 9C lead from South, 7C, 3C, 10C(!) from East! Not the right play on my part, sure, but hard to learn when GIB is revoking. Or do the opps exchange cards under the table depending on your play? Thanks!
